What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Phoibos Narwhal

Owners widely praise the Phoibos Narwhal's 38mm size and slim 11.5mm height for a 200m diver, noting it wears well on smaller wrists and its case shape resembles an integrated bracelet. The aventurine and Howlite dials are described as captivating, and some appreciate the contrast finishing and retro looks. However, some owners criticize misaligned markers and a tilted date window, with one owner finding the hands thick and popsicle-style. The value proposition is debated, with some finding it a good buy at $390 but others considering $480-$490 too much due to a slabby design and difficult-to-size bracelet. On balance, owners find the Phoibos Narwhal appealing for its design and wearability, though quality control and pricing are points of contention for some.

From video reviewers

The unique stone dial is a significant strength. The bracelet's refinement is a weakness. Reviewers disagree on the dial's appeal, with one highlighting its sunburst effect and applied indices, while another focuses on the natural stone variation.

Grand Seiko SBGX359

The Grand Seiko SBGX359 is lauded for its technically advanced 9F51 quartz movement, enabling a compact 33mm x 9.1mm stainless steel case and offering ±10 seconds per year accuracy. Reviewers highlight the refined finishing of its Snowflake dial and 100 meters of water resistance. However, it comes with a US$3,200 price tag, representing a $500 increase over prior 9F models. Overall, reviewers praise the Grand Seiko SBGX359 for its compact dimensions and precise quartz movement at the specified price point.
